In energy-harvesting wireless sensor networks, sensor nodes equipped with a harvesting device scavenge the valuable energy from ambient environments. In this paper, we consider the routing problem of jointly considering the distance, the remaining energy and energy-harvesting capability of sensor nodes with the objective to route the collected data toward the sink node by going through the high-density...
In wireless sensor networks (WSNs), sensor nodes are usually powered by batteries of limited capacity, which results in dynamic changes of available paths for data aggregation due to node failures caused by energy depletion. For transmitting certain amount of data generated by source node, the overall transmission cost is affected by two major factors, using sequence of available paths and amount...
In wireless sensor networks (WSNs), the nodes are usually powered by batteries with limited capacities, which has become one of the main challenges to the wide deployment of WSN-based applications. The overall network lifetime, which is usually determined by the node with the shortest lifetime because of the unbalanced energy consumption, becomes a major issue. Aiming at this, we consider the optimization...
